We explore a small-open economy with overlapping generations to understand what is the determinant of trade pattern in the dynamic trade theory. In the representative agent model (Baxter (1992) ), even if there are two goods and two production factors, opening up to trade leads to perfect specialization. Using the overlapping generations model, we find that the heterogeneity of the economic age...

This paper studies capital accumulation in a slightly altered, explicit OLG model. The fundamental difference with the standard model lies in the initial conditions. If a portion of the initial allocation of the capital stock is not assigned to retirees, the framework allowing for a genuine accumulation of capital is provided. Dynamic aspects of the resulting model are analyzed, including dynam...

This paper addresses the following question: does the stock market influence the process of capital accumulation? If exchanging ownership of firms on a stock market is equivalent to exchanging the ownership of their capital on a capital goods market, then introducing a stock market will not affect the predictions of the real models of capital accumulation–the Ramsey model (1928) if agents are i...

This paper analyzes endogenous economic growth in the model of overlapping generations. There is no bequesl there any externalities. If the t motive, nor are capila the technology is convex, per t growth can occur only if I c economy has at least investment two sectors. This paper shows that the limiting marginal efficiency of I rale determines the potential for growth and that the t of growth ...

In a standard overlapping generations model, active monetary policy reinforces mechanisms that lead to equilibrium indeterminacy and to countercyclical behavior of young-age consumption. The policy rule which minimizes inflation volatility can be active or passive, depending on the characteristics of shocks and the risk aversion of households. Inflation forecast errors are always greater under ...

In this work we develop overlapping generations models (OLG) which explicitly include immigration. In the following, we propose two general equilibrium models. In a first approach, we investigate the effect of a sudden variation in the number of immigrants on the host country to shed light on the welfare effects of immigration for the various generations of the host country’s population. Subseq...

In the classical growth model, with overlapping generations and continuous time starting at −∞, generically there exist a unique equilibrium in the policy-neighbourhood of any balanced growth equibrium as shown in [4]. Policies are endowment perturbations. In this paper we show that, for any such equilibrium selection, welfare is differentiable, and that the derivative at the balanced growth eq...

In the companion paper [2], Balasko and Shell establish existence of competitive equilibrium for a pure-distribution, overlapping-generations economy without money (see, especially, Propositions (3.10) and (3.11) in Section 3). That argument is remarkably simple, but depends critically on some strong hypotheses concerning individual tastes and endowments. In particular, it is assumed that, in a...
